EDGAR H. MORGAN AND CHARLES MORGAN, OF FREEPORT, ILLINOIS, AS- SIGNORSOF ONE-THIRD TO ALBERT BAUMGARTEN, OF SAME PLACE.

COFFEE-MILL.

SPECIFICATION forming part of Letters Patent No. 399,686, dated March19, 1889.

Application filed December 21, 1888. Serial No. 294,262. (No model.)

To all whom it may concern.-

county of Stephenson and State of Illinois,

have invented certain new and useful Improvements in Coffee-Mills; andwe do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it pertains to make and use the same.

Our invention relates to improvements in coffee-mills, and is set forthin this specification, and shown in the accompanying drawings, in whichFigure 1 is a central vertical section of a mill embodying ourimprovements, the plane of section being through the line x 00, Fig. 2.Fig. 2 is a top plan of the cover of the mill, a part of the swingingportion being broken away. Fig. 3 is a horizontal section on the line yy, Fig. 1, the view being upward. Fig.

at is a side view of the central portion of the bridge. Fig. 5 is asection similar to Fig. 1, of a slightly modified construction.

In the drawings, A is the wooden top of a coffee-mill box, and B is ahopper lying below the top and having at its upper edge a horizontalflange, B, lying below the top A, and one or more lugs, B, enteringnotches in the top A, and preventing rotation of the hopper. The hopperhas an open bottom, from which depends a grinding-shell, B and a bridge,C, crosses the opening above the grinding-shell. The bridge is providedwith a central vertical cylindrical opening, C, having opposite notchesC in its walls. The lower faces, C of these walls surrounding theopening C are inclined, as shown in Figs. 1, 3, l. Above the top andresting thereon is a cover composed of a stationary portion, D, and aswinging part, K, pivoted to the part D and adapted to uncover nearlyone-half the hopper, the remainin g portion being at all times covered.A vertical tube, D, is formed integrally with the part D at its center,and extends downward through the opening C in the bridge C. On the lowerend of the tube D are formed two opposite lugs, D, adapted to passthrough the notches C in the bridge when the cover is in properposition, and to pass along the inclined faces C' of the walls about theopening C when rotated in the direction indicated by the arrows of Figs.3, 4. As the lugs D pass along the inclined faces C the cover D andhopper B are drawn together, clamping the top between them. Notches Nare formed at the extremities of the inclined faces, and when the coveris sufficiently rotated they receive the lugs and prevent reverserotation.

Fig. 5 shows a construction in which the hopper is placed above the topA, instead of below it. The bridge and tube are unchanged, and, asbefore, the latter is formed integrally with the cover; but the flange Band the lugs B" are in this case formed upon the grindingshell, and aring, R, is interposed between the hopper and box-top. The parts are connected by the tube D in precisely the same way as in the form shown inFigs. 1, 2, 3, 4.

What we claim is l. The combination, with the top of a coffeeinill box,of a grinding-shell lying below the top and a cover lying above the top,said shell being provided with a dianietrical bridge having a centralopening and said cover with a central tube adapted to pass through saidopening and to lock the parts together when they are rotated withreference to each other.

2. The combination, with the top A, and the hopper B, lying below thetop and having the grinding-shell B and the bridge C, formed with thecentral opening, C, and notches C, of the cover D, resting upon the topand provided with a central tube, D, formed with lugs D", adapted topass through the opening in the bridge and to lock the bridge and covertogether upon the rotation of the cover with reference to the bridge,substantially as set forth.

In testimony whereof we have signed this specification in the presenceof two subscribing witnesses.
